Brief Summary:

For a few years, there has been a keen interest of clinicians and patients for "lighter" antiretroviral strategies based on two- or even single drug regimens rather than the canonical triple therapy, both as initial and maintenance therapy, despite the possibility that ongoing viral replication may occur in some patients under triple-therapy.

We will therefore propose such simplification strategy (DTG/3TC) while maintaining triple-therapy (DTG/ABC/3TC) in a control group and will perform an in depth analysis of the replication-competent reservoir in blood and in tissues as well as measurements of residual viremia and immune chronic activation/inflammation.

Outcome Measures

Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. The impact of dual-therapy Dolutegravir (DTG) + Lamivudine (3TC) at the level of replication-competent reservoir (RCR) in blood and in tissues. [ Time Frame: 1 year ]
    Measurements of RCR in the blood and tissues (rectal biopsies)


Secondary Outcome Measures :
  1. The impact of dual-therapy Dolutegravir (DTG) + Lamivudine (3TC) on residual viremia. [ Time Frame: 1 year ]
  2. The impact of dual-therapy Dolutegravir (DTG) + Lamivudine (3TC) at the level of chronic immune activation/inflammation. [ Time Frame: 1 year ]
  3. The correlation between blood and tissues RCR in a high number of patients under suppressive antiretroviral therapy. [ Time Frame: 1 year ]
  4. The level of clonal expansion in the blood and tissue RCR [ Time Frame: 1 year ]
  5. The correlation between the size of the blood/tissues RCR and the level of chronic immune activation/inflammation. [ Time Frame: 1 year ]
